BACKGROUNDAlthough smoking causes serious respiratory diseases and cancers, it is difficult to get smokers to quit smoking. Nicotine is the effective ingredient in cigarettes. Nicotine is a micro-molecular alkaloid which is basically harmless to humans at low dosages. Tar is the major harmful substance in tobacco. Tobacco tar contains thousands of ingredients, dozens of which are carcinogenic.
Cigarette substitutes have used relatively pure nicotine in patches, chewing gum and aerosols. Still disadvantages remain with cigarette substitutes or products for helping smokers to quit smoking.
SUMMARY OF THE INVENTIONAn improved electronic cigarette has a battery assembly, an atomizer assembly and a cigarette bottle assembly. The battery assembly connects with one end of the atomizer assembly, and the cigarette bottle assembly is inserted into the other end of the atomizer assembly, thus forming one cigarette type or cigar type body. Use of the electronic cigarette reduces cancer risks and fire hazards while providing a simulated smoking experience.

As shown in
The sensor (207) may be switch sensor made of elastic alloy slice, a linear output Hall sensor, a semiconductor force-sensitive chip, a semiconductor matrix thermoelectric bridge chip, capacitance or inductance sensor. The indicators (202) include two red LEDs. The lithium ion battery (203) may be either a rechargeable polymer lithium ion battery or a rechargeable lithium ion battery. The external thread electrode (209) is a gold-coated stainless steel or brass part with a hole drilled in the center. The silica gel corrugated membrane (208) may alternatively be made of fluorinated rubber, butyronitrile rubber, or elastic alloy film.

The atomizer (307) may be a capillary impregnation atomizer as in
As shown in
(403), negative pressure forms on the silica gel corrugated membrane (208) through the air intake hole (503) and the primary and secondary negative pressure cavities (210, 301). The silica gel corrugated membrane (208), under the action of suction pressure difference, distorts to drive the switch spring (212) and sensor (207), thus switching MOSFET electric circuit board (205). At this moment, the indicators (202) are lit gradually; the lithium ion battery (203) electrifies the heating body (305) inside the atomizer (307) through MOSFET electric circuit board (205) as well as the internal and external thread electrodes (302, 209).
The heating body (305) inside the atomizer (307) produces heat. The fiber (402) inside the cigarette liquid bottle (401) contains cigarette liquid, which soaks the micro-porous ceramics (801) inside the atomizer through the fiber (402). The air enters through the air intake hole (502), passes through the run-through hole on the air-liquid separator (303), and helps to form air-liquid mixture in the spray nozzle (304) of the atomizer (307). The air-liquid mixture sprays onto the heating body (305), gets vaporized, and is quickly absorbed into the airflow and condensed into aerosol, which passes through the air intake hole (503) and suction nozzle (403) to form white mist type aerosol.
When suction stops, the switch spring (212) and sensor (207) are reset; the atomizer (307) stops working; the indicators (202) gradually die down. When the operation times reaches the pre-set value, the atomizer (307) provides a work delay of 5-20 seconds per time, so as to remove the micro-dirt accumulated on the heating body (305).
Besides the micro-porous ceramics, the liquid supply material of the atomizer (307) may also be foamed ceramics, micro-porous glass, foamed metal, stainless steel fiber felt, terylene fiber, nylon fiber, nitrile fiber, aramid fiber or hard porous plastics. The heating body (305) is made of the micro-porous ceramics on which nickel-chromium alloy wire, iron-chromium alloy wire, platinum wire, or other electro thermal materials are wound. Alternatively, it may be a porous component directly made of electrically conductive ceramics or PTC (Positive Temperature Coefficient) ceramics and associated with a sintered electrode. The surface of the heating body(305) is sintered into high-temperature glaze to fix the zeolite grains, which are made of natural zeolite, artificial non-organic micro-porous ceramics or aluminum oxide grains. The cigarette liquid bottle (401) and suction nozzle (403) in the cigarette bottle assembly are made of non-toxic plastic. The fiber (402) inside of them is made of polypropylene fiber or nylon fiber to absorb cigarette liquid. In the battery assembly, there is a fine hole (501) on the indicator cap (201) for balancing the pressure difference on both sides of the silica gel corrugated membrane (208).
The cigarette liquid contains 0.1-3.5% nicotine, 0.05-5% tobacco flavor, 0.1-3% organic acid, 0.1-0.5% stabilizer, and propanediol for the remaining.
The primary and secondary shells (211, 306) are made of stainless steel tube or copper alloy tube with baked-enamel coating of real cigarette color.
As shown in
For charging the lithium ion battery (203), the screw thread electrode (601) matches the external thread electrode (209) on the battery assembly, so that it may be used as the charging interface.

As shown in
The fiber (402) inside the cigarette liquid bottle (401) contains cigarette liquid, which soaks the micro-porous ceramics (801) inside the atomizer through the fiber (402). The air enters through the air intake hole (502), passes through the run-through hole on the air-liquid separator (303), and helps to form air-liquid mixture in the spray nozzle (304) of the atomizer (307). The air-liquid mixture sprays onto the heating body (305), gets vaporized, and is quickly absorbed into the airflow and condensed into aerosol, which passes through the air intake hole (503) and suction nozzle (403) to form white mist type aerosol.
